Speed Control Linkage problems of the 2001 Ford Focus

Driving with cruise control set at 60 mph when car accelerated gaining speeds over 75. I pulled over, shut down engine, lifted hood and saw accelerator linkage was stuck. I cleared linkage, started engine and car ran normally. This happened 3 more times on later dates with cruise control engaged. Car starts accelerating until I stop vehicle, shut off engine, and free up linkage/metal.

My daughter was driving on the highway. Traffic was trying to merge, and she was blocked in on the left. She accelerated a little to get ahead of the merging traffic. At that time the throttle stuck wide open and would not release. She stated that when she tried to stop the car with the brakes, it would not slow down even though she was pushing as hard as she could on the brake pedal. She placed the gear shift in neutral and was able to stop the car. She came to a stop at the side of the road and shut the car off. The rpms were at 7000 before she shut the engine off. Upon restart, the engine continued to race to 7000 rpm. She was able to get the throttle un-stuck by pushing the pedal to the floor and releasing. She drove the car to a sears auto center, where the technician found the throttle linkage malfunctioning. He could not fix the problem, and could not guarantee that it would not happen again. We elected to leave the car there, and have it towed to a Ford dealership in the morning. It was a very scary and potentially dangerous event.

Aic valve replaced 2 times car same: throttle cable replaced 1 intermttent problems, still. They told me "this is the way it is" its dangerous?.

Throttle cable appears to be too long - cable has kinked and causes car to hesitate acceleration. When the car does accelerate it is sudden and could be dangerous under certain driving conditions (heavy traffic, ice on roadway). It appears my car is not the only car in for the exact same problem - the part had to be special ordered.
